EOALL WHOM IT MAY eononnn;

Be it known that I, Ennnnnnn FABER, of .133 William street, New York, county and State of New York,

have invented 'a newend useful Improvement in Pencils; and I do hereby declare that the following is s full, clear, and exact description thereof; which will enable those skilled in the art to mehesnd use the-same, referenceheing had to the accompanying drawing, forming part of this specification; in ivhieh drawing-- Figure 1 represents a side elevation of this invention.

Figure 2 is a longitudinal section thereof.

Similar letters indicate,corresponding parts.

This invention relatcsito a pencil which is provided at one end withn rounded convex head, formed by dipping IE pencil in a suitable enamel or compound in such 'o-mnnner that on lifting the pencil out of the enaniel, the drop-Adhering to its loner and forms the required head, and thereby not only a new and distill gnishing nppenrnnce is given to my pencils, but also thecnd' is protected against the influence of the atmosphere andof moisture, and the operation of cutting elf the pencil at one end is saved.

A represents opencil, 'which is made inth eusual inrumer by inserting a piece of leed or graphite into at wooden casing, After the lead hns heen secured in its casing, the pencil thus formed is varnished, and finally the ends hre cut oil square, to give to the pencil a. good appearance. Instead of varnishing the pencils have recently adopted the plan of enninelling them, as follows: I immerse the pencils endwise in a. compound of ,Prussian blue, linseed oil, and binoiride of manganese, or any other similar compound, known commonly by the term "japan," and having the property that the some will produce a glossysuri'sce when baked; 'When a pencil is immersed into this compound and cnrefully withi'lrewn, it drop adheres to its lower end. I then bake the pencil," and after it has bec'orne dry, I repeat the operstion of dipping again and again until I obtains convexishaped head, q, at the end of the pencil, as clearly shown in the drawing. By this head the pencil receives a new anddi'stinguishing appearance; and, furthermore, hy' the meniscus-shaped head the end of the pencil is protected against-the influence of the atmosphere, and the operation of cutting on" the pencil at that end, after the shine has been enamelled, is saved.

Whot I claim as new, and desire to secure by-Letters Patent, is- A pencil, provided with arounded convex head, formcd by dipping said pencil in asuitable compound, sulisientially nsjherein set forth.
